GERI-IARD MATHIS, OF BROOKLYN, NEW YORK.

SHADE-ROLLER.

SPECIFICATION forming part of Letters Patent No. 714,005, dated November18, 1902.

Serial No. 118,771. (No model.)

T0 at whomit may concern.-

Be it known that I, GERHARD MATHIS, a citizen of the United States,residing in New York, in the borough of Brooklyn and State of New York,have invented certain new and useful Improvements 'in Shade-Rollers, ofwhich the following is a specification.

This invention relates to shade-rollers of the self-acting class; and itrelates particularly to an attachment mounted upon the spring-actuatedpintle, which serves as a keeper by cooperating with the shade-bracket,so as to retain the shade-roller in position in the bracket, and therebyprevent the same from being accidentally displaced in the action of theroller.

To this end theinvention consists of ashaderoller provided with aspring-actuated pintle, a keeper loosely mounted on said pintle, saidkeeper having a wing projecting at one side and a bracket. for receivingthe end of said spring-actuated pintle, said wing being adapted tocooperate with said bracket, so as to prevent the removal of the pintle,as will be more fully described hereinafter and finally pointed out inthe claims.

In the accompanying drawings, Figure 1 is a front elevation of thespring-actuated end of a shade-roller having my attachment appliedthereto. Fig. 2 is an end view of the roller. Fig. 3 is a detail view ofa bracket; and Figs. at and 5 are vertical transverse sections,respectively, on lines at 4 and 5 5, Fig.1.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the shade roller, which isprovided with the spring-actuated pintle a, the latter being attached tothe roller in the usual manner. The bracket B,that is provided with aslotted barrel b, is of usual construction for receiving the rectangularend of the spring-actuated pintle a. The pintle 0 adjacent to the end ofthe roller is provided with an annular flange a, and between said flangeand the end of the roller is loosely mounted on the pintle a keeper,which consists of a diskshape'd portion 0, having a wing c that projectsto one side from a portion of its edge. The wing 0 extends beyond theplane of the front surface of the barrel of the bracket and is disposedbelow the barrel in close proximity thereto when the pintle is seated inthe the wing of the keeper is held in the position above the pintle, asshown by dotted lines in Fig. 1, the pintle being thereby permitted todrop into the slotted barrel of the bracket and become seated therein inthe usual manner, whereupon the keeper is turned around on the pintle toa position below the barrel of the bracket, as clearly shown in Figs. 1and 5. In this position the wing extends beyond the front surface of thebarrel of the bracket, so as to engage with-the latter in order topreventanyupward movementof the pintlein the recess of the bracket, andconsequently preventing the accidental displacement during the action ofthe shade-roller. When it is desired to remove the shade-roller from thebracket, the keeper is turned to the uppermost position, as shown bydotted lines in Fig. 1, so that the Wing is moved out of the path of thebarrel of the bracket to permit the ready removal of the pintletherefrom.

By means of this simple and inexpensive attachment the accidentaldisengagement of the shade-roller from its brackets is effectivelyprevented. The attachment is easily operated, so that the setting up ofthe shaderoller and its removal from the brackets are accomplished withfacility.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a shade-roller, the combination, of a spring-actuated pintle, abracket for said pintle, and a swinging keeper on said pintle adapted tocooperate with said bracket for retaining said pintle in the latter,substantially as set forth.

2. In a shade-roller, the combination, of a spring-actuated pintle, abracket having a slotted barrel, and a movable keeper on saidpintle'adapted to engage the exterior portion of the barrel of thebracket, substantially as set forth.

3. The combination, with a shade-roller, of

my invention I have signed my'nam'e in presence of two subscribingwitnesses.
